A regular slot would be great. I know I'm in the minority here but (most likely stemming from the fact that I couldn't watch it during its original run) MG90 was a favorite.
I enjoyed it then and I still enjoy it. I think, when it comes down to the format, that’s the best attempt that was made. Sure, the original 7x format works well too, but the addition of Match Up was a good touch.
Considering Buzzr is running/has run the CBS Daytime, MG PM weekly and the Nighttime MG 5-a week shows in groups, why not do a 2-hour Match Game block with one of each series with MG 90 rounding out the 4th spot? I'm pretty sure most of the Rayburn shows that can be aired are converted to digital, so Shaffer's version shouldn't be too hard to convert.
Love to see that as well with a 2-hour block of TTTT: The Colliers, The Moores/Garagiolas, the Wards, and the Elliott/Swann/Trebeks.
Some versions will recycle quicker than others, but by that time, Buzzr usually shuffles the schedule anyway.
